So I recently upgraded my irons to the Titleist Ap2's and was blown away by how good they were.  I was playing png Irons and the R11 driver and 3 wood.  I really couldn't hit the R11 consistently and after reading all of the rave reviews about the 910 D2 driver I had to try it.  So I hit it at a local driving range and ended up getting fitted to the D2 with the Rip 70 stiff shaft.  All i can say is WOW, it is very accurate and long and even when I miss hit it the ball stays in play.  Thanks Titleist for awesome products, I wish i would have switched over a couple of years ago.
